<h3>Notes</h3>

The spec indicates that there should only be a center longitude, not a 
center latitude.  Intergraph includes a latitude, so I have included it
here, but if not specified it should be taken as zero. <p>

Intergraph uses NatOriginLat and NatOriginLong instead of ProjCenterLat/Long.
<p>

Intergraph also supplies a scale at the origin, which isn't in the spec.
I am ignoring this for now, but eventually a pass should be made adding
scale as an option for any projection it can be made to work for as per
Peter Laskowski's suggestion.<p>
